Abstract

An aircraft propulsion system (20) includes a compressor section (26), a combustor section (28), and a fuel system assembly (36). The compressor section (26) includes a plurality of inlet guide vanes (42), an inlet guide vane actuator (IGVA) (120), and an IGVA servo (118). The IGVA (120) is operably coupled with the plurality of inlet guide vanes (42). The IGVA servo (118) is connected in fluid communication with the IGVA (120). The combustor section (28) includes a combustor (44). The fuel system assembly (36) includes a jet fuel system (86) and a hydrogen fuel system (88). The jet fuel system (86) is connected in fluid communication with the combustor (44). The hydrogen fuel system (88) is connected in fluid communication with the combustor (44) and the IGVA servo (118). The hydrogen fuel system (88) is configured to direct the hydrogen fuel to the IGVA servo (118) to control a position of the IGVA (120).
